Some cells release active signaling proteins when membrane-bound precursor proteins are cleaved by proteolytic enzymes. The signaling proteins can then bind to receptors on the surface of a target cell, thereby activating an intracellular signaling pathway and eliciting a response from the target cell. This mechanism of activating receptor-binding signaling proteins has been observed in a variety of organisms from bacteria to humans. Many of the enzymes responsible for proteolysis of membrane-bound precursor proteins have been isolated and characterized.


Required:

What questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species?

Answers

Answer:

Following questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species:

Are the genes encoding the proteolytic enzymes expressed in the same cell types in all species?  Once the precursor proteins of different species are cleaved, do the active signaling proteins bind to  the same receptors on different target cells? If a proteolytic enzyme from one species is incubated with a precursor protein from another species, does correct cleavage occur? Are the proteolytic enzymes synthesized in the rough endoplasmic reticulum of all species?

Which amino acids would be found in the mutation protein

Answers

Answer:

Amino acid sequence: Valine- Threonine- Aspartic acid- Cysteine- Serine- Cysteine- Stop.

Explanation:

This question is describing the process of translation, which is the second stage of protein synthesis. Translation is the process whereby a mRNA template is used to produce amino acids, which forms a sequence that will eventually become protein.

The mRNA sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. According to this question, using the genetic code table, the given DNA sequence is as follows:

DNA: CAT- TGG- CTA- ACG- TCG- ATA- ATC- GTC- GGT- AC

RNA = GUA- ACC- GAU- UGC- AGC- UAU- UAG- CAG- CCA- UG

Amino acid sequence: Valine- Threonine- Aspartic acid- Cysteine- Serine- Cysteine- Stop.

Which of the following statements about diffusion is FALSE?

Question 39 options:

smaller surface area of the cell membrane increases the diffusion rate


small molecules travel much faster than larger molecules


a higher concentration gradient increase the diffusion rate


higher temperatures allow for molecules to move quickly across the cell membrane

Answers

Answer:

smaller surface area of the cell membrane increases the diffusion rate

Explanation:

Diffusion is the process by which molecules move from a region of high concentration to a region of low concentration until there is an even distribution. The rate at which diffusion occurs is dependent on certain factors as follows:

- Temperature: An increase in temperature increases the rate of diffusion because there is an increase in the kinetic energy of the molecules in response to temperature.

- Surface area of the cell: A cell with large surface area undergoes diffusion at a higher rate than a cell with small surface area.

- Concentration gradient: The difference in concentration of the molecule on each side of the membrane is the CONCENTRATION GRADIENT, which when increased also increases the rate of diffusion.

- Size of molecules: small molecules tend to travel faster than larger ones, hence, they diffuse faster.

Answers

Answer:

Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O2) and CO2. O2 generally diffuses into cells because it is more concentrated outside of them, and CO2 typically diffuses out of cells because it is more concentrated inside of them.

(b) Using the template of the phylogenetic tree, circle the lineages that share node

Answers

Complete question:

(b) Using the template of the phylogenetic tree, circle the lineages that share node A. You will find the tree in the attached files.

Answer:

The Lineages that share node A are  

Chinese river dolphinAmazon river dolphinLa Plata river dolphinDolphinsNarwhalPorpoises

Explanation:

The phylogenetic tree is composed of,

Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.

- Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.

- Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.

There are also different phylogenetic relationships between lineages.

Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.

Firstly the question is incomplete the image is not attached with it which shows the phylogenetic tree.

The Lineages that percentage node A are

Chinese river dolphin river dolphinLa Plata river dolphinDolphinsNarwhalPorpoises

The phylogenetic tree consists of:

Lineages → These are the taxonomic companies of hobby located withinside the extremes of the traces referred to as branches.Nodes → These are the ramification points, that are additionally called divergence points. They constitute the area of the maximum latest not unusual place ancestor.Root → This is the older not unusual place ancestor that every one lineages percentage. The first one withinside the tree.- Two or extralineages are extra associated with every difference in the event that the percentage a latest not unusual place ancestor. In this manner, all of them diverge from the equal node.

Two or extra lineages are much less associated with every difference in the event that they lack a latest not unusual place, ancestor. This is, the node from which those lineages diverge is located a long way away withinside the tree.

There also are one-of-a-kind phylogenetic relationships among lineages.

Apomorphies → Occur while the worried lineages percentage a trait that they inherited from their maximum latest not unusual place ancestor. This trait developed for the primary time on this ancestor. → This dating is a homology.

Plesiomorphies o( while the worried lineages percentage a trait inherited from a not unusual place ancestor, however, this is older regarding the prevailing developments exhibited via way of means of different descendants of the equal not unusual place ancestor. This dating is a homology.

Homoplasy Lineages percentage is a trait that developed independently in every group. → This dating is an analogy.

What is the phylogenetic tree?

The phylogenetic tree is the branching diagram showing the evolutionary relationships among various biological species.
